摘要: 为优化冷冻和解冻方法,提高冷冻效果,本试验比较了不同冷冻速率(-100 ℃ 10 min、-120 ℃ 10 min、-140 ℃ 10 min)和不同解冻温度(37 ℃ 30 s、45 ℃ 30 s、52 ℃ 30 s、60 ℃ 30 s)对猪精液冷冻效果的影响。结果表明,采用-120 ℃熏蒸10 min,解冻后精子活力为0.36,质膜完整率和顶体完整率也优于其他2组,且差异显著(P<0.05)。采用37 ℃ 30 s方法解冻,精子活力、质膜完整率显著高于其他3组,顶体完整率也高于其他3组,但差异不显著(P>0.05),其畸形率最低和60 ℃ 30 s组差异明显(P<0.05),但与45 ℃ 30 s组和52 ℃ 30 s组差异不显著(P>0.05)。因此,采用-120 ℃平衡10 min冷冻,37 ℃ 30 s水浴解冻方法更为适合0.25 mL细管猪冻精解冻。

Abstract: For improving the freezing and de-freezing methods for boar semen further, it was aimed to investigate the effect of different freezing frequency(-100 ℃ 10 min,-120 ℃ 10 min,-140 ℃ 10 min) and thawing temperature(37 ℃ 30 s,45 ℃ 30 s,52 ℃ 30 s,60 ℃ 30 s) on cryopreservation of boar semen. The results showed that the sperm motility, plasma integrity, normal acrosome rate by freezing treatment with -120 ℃ 10 min, were all significantly higher than those of the other three groups respectively(P<0.05). The sperm motility, plasma integrity, normal acrosome rate by thawing treatment with 37 ℃ 30 s, were not significantly higher than those of the other three groups respectively(P>0.05), but the difference of the sperm abnormality in the treatment with 60 ℃ 30 s was significant(P<0.05), but with 45 ℃ 30 s and 52 ℃ 30 s were not significant(P>0.05). Therefore, it could be concluded that the combination of freezing by -120 ℃ 10 min and thawing by 37 ℃ 30 s were appropriate to frozen-thawed 0.25 mL pipettes of boar semen.
